  • Publication number: 20250208231
    Abstract: Current sharing in a power system having multiple PSUs comprises generating and supplying a first power and a second power to a load, and sensing a remote voltage value received by the load based on an accumulation of the first and second powers. The method further comprises determining, by the first PSU, local voltage and current values of the first power, a real impedance value of the first PSU based on the remote voltage value and the local voltage and current values of the first power, and a virtual impedance value of the first PSU based on the real impedance value of the first PSU and a reference impedance value. The method further comprises controlling generation of the first power by the first PSU based on the virtual impedance value of the first PSU.

  • Patent number: 12265831
    Abstract: A method is provided of swapping code execution among multiple microcontroller code banks. The microcontroller has computer-readable memory, a central processing unit, and an interrupt controller. The method comprises executing an instruction to process a first pointer storing an address location of a first application within a first code bank of computer-readable memory. The first application is executed based on processing the first pointer. The method also comprises replacing the address location of the first application stored within the first pointer with an address location of a second application stored with a second code bank of the computer-readable memory. The instruction to process the first pointer is executed to process the address location of the second application to execute the second application without stopping operation of the interrupt controller.
